Title: Improvements in or relating to Means for Starting Internal Combustion Engines.
Inventor: BIJUR JOSEPH
IPC: F02N15/06
Filed: 1917-10-29
Abstract: 113,431. Bijur, J. Feb. 1, 1917, [Conven tion date]. Turning-gear.-An engine starter comprises a nut 9 cooperating with the threaded shaft 2 of the starting-motor 1 and a pinion 6 adapted to engage and drive a part 7 of the engine to be started; the pinion 6 is movable freely on an unthreaded part of the shaft 2, and is connected to the nut 9 by means of a spring 17 between the nut 9 and a flange 18 on the pinion and a barrel 16 having a toothed flange 19 engaging the teeth of the pinion. The barrel 16 is driven from a flange 10 of the nut 9 by means of two friction clutches, one comprising a metal annulus 22 pressed against the flange 10 by a spring washer 39 held in place by a sleeve 38, and the other comprising a leather washer 11 riveted to a metal annulus 13 and acted upon by the spring 17. The annuli 22, 13 have peripheral lugs engaging and driving the barrel 16. The nut 9 and cooperating parts are retained in the barrel 16 by a cap ring 26. Longitudinal projections 27 extend through slots in the ring 26 and have openings engaged by integral lugs 30 on the periphery of a spring-metal split ring 29, Fig. 5, which is narrowest at its dividing point to facilitate snapping into place. On starting the motor 1, the nut 9, barrel 16, and pinion 6 move to the right against a light spring 34. If the teeth of the pinion 6 and the engine member 7 meet end to end, the arrest of the pinion 6 compresses the spring 17, tightening the clutch 11, 12 and effecting the rotation of the pinion to bring the teeth into mesh. The pinion then advances into complete mesh with the member 7 and drives it, the movement into mesh being cushioned and the clutch 11, 12 tightened by a pair of dished washers 33 which receive the impact of the annulus 13. These washers are preferably of ferro-silicomanganese. The return of the mechanism, when the engine starts, is cushioned by a spring 64 acting upon a slidable sleeve 61, which strikes a fixed stop 65. The accidental return of the mechanism towards the engine member 7 is prevented by the friction between the spring 64 and adjoining parts, and by the spring 34, which causes the nut 9 to bind somewhat on its threaded shaft. In a modification, Fig. 8, the nut 70 acts directly on the barrel 16<1> and the spring 17<1> without the interposition of clutches. The movement into mesh is towards the motor and is cushioned by three pairs of dished washers, and the return movement is cushioned by a spring 76 carried by the end-stop 78. The bore of the nut is unthreaded at 67<1> to enable it to bear against the dished washers.

Abstract: 923,707. Separation of actinide elements. UNITED STATES ATOMIC ENERGY COMMISSION. May 2, 1961 [July 20, 1960], No. 15851/61. Class 39 (4). Californium is separated from curium in an aqueous mineral acid solution containing the metals in their trivalent states by adjusting the acidity of the solution to 0.01-17, contacting the solution with a substantially water-immiscible organic solution of an acidic phosphoric acid ester or a half ester of organophosphonic acid, whereby californium is preferentially taken up by the organic phase, and separating the organic and aqueous phases. The process may also be used for separating yttrium from californium or cerium from berkelium. Preferred organic esters are 2-ethyl hexyl hydrogen phenyl phosphonate and 2-ethyl hexyl hydrogen chloromethyl phosphonate; 2-ethyl hexyl hydrogen 2-ethyl hexyl phosphonate, bis (2-ethyl hexyl) phosphoric acid, and bis (octyl phenyl) phosphoric acid may also be used, preferably with the addition of a small quantity of tris (2- ethyl hexyl) phosphate. Organic diluents specified are carbon tetrachloride, benzene, toluene, and xylene. Neutron-bombarded plutonium may be dissolved in nitric, hydrochloric, perchloric, or sulphuric acid and extracted with the organic solvent at room temperature using a batch or countercurrent process. Californium may be back-extracted from the organic phase with 1-6 M mineral acid, and then re-extracted with the organic solvent. The aqueous phase from the first extraction may be extracted with an organic solution of iso-octyl pyrophosphate to obtain a salt-free curium fraction. Examples I and II describe the separation of californium and curium, Example III yttrium 91 and californium, and Example IV cerium 144 and praseodymium 144 from berkelium. U.S.A. Specification 2,859,095 is referred to.

Title: Process for the manufacture of new compounds from indene and phenols
IPC: C07C37/14
Filed: 1927-06-14
Abstract: 297,075. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). June 14, 1927. Indene-phenol condensation products.-Indene and mono or polyhydric phenols are condensed by treatment with a halogen acid. Instead of indene, an indene derivative or a substance containing indene, e.g. a solvent naphtha fraction from which phenols and bases have been removed may be used. The new products are suitable as intermediates, disinfectants and as bases for lacquers. According to an example, indene and phenol are condensed by means of hydrochloric acid and the resulting oil, after purification by distillation in vacuo is dissolved in a hydroaromatic hydrocarbon whereby crystals of hydrindylphenol are obtained. A further product, a viscous oil insoluble in alkali, is obtained on evaporation of the solvent from the mother liquor. The hydrindylphenol gives with aromatic bases such as hexamethylenetetramine well defined compounds. In other examples, the following pairs of components are condensed, using gaseous, aqueous or alcoholic hydrochloric acid as condensing agent : a solvent naphtha fraction and crude cresol, indene and anaphthol, a-xylylindene and crude cresol or phenol, and finally indene fractions and o-cresol or resorcinol. The products are resins and viscous oils which usually may be resolved into alkalisoluble and alkali-insoluble portions. Aminonitro- and chlor-phenols, thymol and pyrocatechin are also mentioned as phenols that may be used. a-Xylylindene is prepared by the interaction of indene and technical xylylchloride in the presence of powdered caustic potash at elevated temperatures.
